Is this a scam

[VenessaRichter]

Someone bought something from me through PayPal. I set up a account, they put $250 in to pay. Now it says I have to open a business account and expand my limit to $1000. He is suppose to put another $750 in so in total his share is $1000. And Im suppose to put $750 in bitcoin, then send that receipt to paypal for the transaction to go through. Leaving me with $1000 to collect. I have been receiving emails from a paypal email address starting with <Removed>

Does this seem like a scam?

SCAM.

They encourage you to accept a 'direct' Paypal payment and may ask you to send the item internationally.
No funds or activity of the transaction shows in your Paypal account and any emails 'may' go into your junk or spam folders.

You will get/got a "fake" email that looks as though it is from paypal.....it isn't because they don't actually have a Paypal account and have no intention of paying you.
It will say the buyer has paid ...you won't have been paid.
They will tell you that the payment is released when you provide paypal with a tracking/shipping number......this won't happen.

Or once you have sent and they know you have become a victim they may again send you 'fake' Paypal emails stating they sent too much and you have to refund BEFORE the funds are released to your balance or you have to send a western union or bitcoin payment to pay customs fees etc.

Paypal NEVER tell you to send an item before the payment is showing in your paypal account.
Paypal do not tell you to send trackable, they advise it for selling protection but it is not compulsory.
Paypal NEVER expect you to use a rival money transfer service eg Moneygram or Western Union/bitcoin etc.
